I will give brainliest to the best answer to this question: Each year, the Department of Water Works measures the chloride conce

Maslowich

Answer:

The total change that will likely occur in 2 years is $=-3\frac{2}{3}$ mg/L

Step-by-step explanation:

Given : The first year, they found the chloride concentration changed by $-1\frac{3}{5}$ mg/L .

It is estimated that the chloride concentration will change $-2\frac{1}{15}$ mg/L the next year.

To find : What is the total change that will likely occur in 2 years?

Solution :

The chloride concentration changed by $-1\frac{3}{5}=-\farc{8}{5}$ mg/L in first year.

The chloride concentration will change $-2\frac{1}{15}=-\frac{31}{15}$ mg/L the next year.

The total change that will likely occur in 2 years is

$=-\frac{8}{5}+(-\frac{31}{15})$

$=\frac{-24-31}{15}$

$=\frac{-55}{15}$

$=\frac{-11}{3}$

In a mixed fraction - $=-3\frac{2}{3}$ mg/L
